Question

Can the unseen/abstract/spiritual (unknowable, immeasurable) be separated from the seen/material/physical (knowable, measurable)? If the mind cannot exist without the brain, nor consciousness without electric sensation/connection, then isn’t the unknown/spiritual intertwined with the known/physical? Can psychedelics help Western society overcome an extreme secular reaction to religion and return to the mystical/metaphysical through the physical?

Thoughts?
